CVE-2026-81650 Details
Description
The Photo Gallery, Sliders, Proofing and WordPress plugin before 4.5.0 does not correctly validate the extensions of files extracted from an uploaded archive, due to a variable being reused as a loop counter so that the check always passes, allowing users granted its gallery-management capability by an administrator to write arbitrary files into a web-accessible directory and, on hosts that execute them, run arbitrary code.
A vulnerability exists in the NextGEN Gallery WordPress plugin in versions prior to 4.5.0. The issue arises because the plugin fails to properly validate file extensions of items extracted from uploaded ZIP archives. This flaw allows users with gallery-management permissions to upload arbitrary files to a directory accessible via the web. On servers that execute these files, it could lead to the execution of arbitrary code.
Users are advised to update the NextGEN Gallery WordPress plugin to version 4.5.0 or later.
